Answer:
It is either the first one or the third one but I can't read the rest of the question to make sure which one is right...Nvm It's the first one, I was zoomed in
Step-by-step explanation:
By definition, the area of the trapezoid is:
A = (1/2) * (AB + CD) * (h)
Where,
AB, CD: bases of the trapezoid
h: height
Substituting values:
A = (1/2) * (19 + 19) * (14)
A = 266 units ^ 2
Answer:
The area of the special trapezoid is:
A = 266 units ^ 2
The complement of the given set is:
A* = {-1, 0, 1, 4, 5}

How to find the complement of the set?</h3>
For any set A on a universal set U, such that:
A ⊂ U.
The complement of A is the set of all the terms on U that do not belong to A.
Here we have:
U = {-3, -2, -1, 0, 1, 2, 3, 4, 5, 6, 7}
And the given set is:
A = {-3, -2, 2, 3, 6, 7}
Then the complement of A is:
A* = {-1, 0, 1, 4, 5}
(all the elements of U that are not in A).

Answer:
Surface Area = (2 • π • r²) + (2 • π • r • height)
Surface Area = 2 * 3.14 * 3*3 + 2 * 3.14 * 3 * 15
Surface Area = 56.52 + 282.60
Surface Area = 339.12

Step-by-step explanation:
Let
be a rectangular
matrix with column vectors
, i.e.
Then we have
and the product of the two is
Because the columns of
are orthonormal, we have
which means
reduces to an
matrix with ones along the diagonal and zero everywhere else, i.e.
where
denotes the identity matrix. This means the solution to
is given by
